This document is intended to help hardware designers integrate the CobraNet
into an audio system design. It covers the CS18100x, CS18101x, CS18102x, CS49610x,
CS49611x, and CS49612x members of the CobraNet
“x” is the ROM version (ROM ID). This document also describes the CM-2 module with
schematics, mechanical drawings, etc.
CobraNet is a combination of hardware (the CobraNet interface), network protocol, and
firmware. CobraNet operates on a switched Ethernet network and provides the following
additional communications services.
The CobraNet interface performs synchronous-to-isochronous and isochronous-to-
synchronous conversions as well as the data formatting required for transporting real-time
digital audio over the network.
The CobraNet interface has provisions for carrying and utilizing control and monitoring
data such as Simple Network Management Protocol (SNMP) through the same network
connection as the audio. Standard data transport capabilities of Ethernet are shown here
as unregulated traffic. Since CobraNet is Ethernet based, in most cases, data
communications and CobraNet applications can coexist on the same physical network.
